Hair-drying machine



Aug. 12, 1930. A. TROCCOLI HAIR DRYING MACHINE Filed Feb. 19, 1929 .I77ve17ib7 Patented Aug. 12, 1930 PATENT OFFICE ACHILLE TROCGOLI, OF BELMONT, MASSACHUSETTS Ham-DRYING Macnnm Application filed February 19, 1929. Serial No. 341,130.v

My present invention relates to hair drying machines and more particularly to such machines utllizing hot or warm arr as the drying medium and a source of power to supply said heated air under pressure.

With the use of present hair drying machines of which I am aware, it requires a considerable length of time, approximately an hour, to dry the hair. Thls is particu arly true when permanent wavin or finger wavmg is performed, due to the act that various ointments are utilized to set the waves, and these ointments form a coating or film on the hair through which it is difficult to penerate with the heated air.

An important object of the present inveri tion, therefore, is the provision of a machine which will effect a complete penetration of all the hair of the head with the heated air, thus resulting in greatly reducing the time required for drying. By the use of my novel machine I am enabled to completely dry a head of hair in approximately ten minutes. The advantages of this quick drying feature are numerous, and will be readily appreciated by those skilled in the art, as well as by those being treated by said machine.

Another object of the invention is to provide means to direct the heated air first to those parts of the hair which are the wettest, that is, the sides, extreme front and back.

Another object of the invention is the provision of such a machine, so constructed and arranged, that the heated air will have very little, if any, contact with the face and neck of the person under treatment.

In carrying out my invention I utilize a funnel or helmet having direct connection to a source of heated air, preferably introduced into the funnel under pressure, as by an electric fan, an electric heater being interposed in the path of the air to heat the same as it passes. The outer end' of this funnel or helmet is enlarged, forming a chamber to reoeive a portion of the head. Within this first helmet is a second helmet, ada ted also to receive a portion of the head 0 the person under treatment, said second funnel having upon the air being introduced into themachine and will direct said current of heated air downwardly over the front, sides and back of the hair. The outlet from the second or smaller helmet is piped to the side of the motor which serves as an inlet, and the fan which blows the air from the motor through the first funnel will act to suck the air from the second funnel or helmet. This sucking action will operate, after the heated air has passed a slight distance below the first funnel, to draw said air upwardly, under and through the hair at the front, sides and back, effecting a thorough drying action of said hair, and the' air will then be directed back to the blower fan and again passed through the first funnel, so that a continuous circula- REISSUED tion of the heated air is effected. This arrangement also requires less heating capacity on the part of the heating unit, as the air will already be pre-heated before contact with said heater, thus resulting in an economy of operation of this machine.

If desired, I may position, in the second or internal helmet, a perforated bafiie plate, to direct the major portion of the air passing upwardly through said second helmet around the sides thereof, but still permitting sufiieient heated air to contact with the top of the head to thoroughly dry the hair at that point.

Thus an even. quick drying-of all the hair on the head is effected inan extremely short space of time, far quicker than has heretofore been considered possible, and without thely in the present application.

The above and other features and objects of the invention, details of construction, combinations of parts, and advantages, will be hereinafter more fully pointed out, described and claimed.

Referring to the drawings, illustrating a preferred embodiment of the invention,

Fig. 1 is a side elevation of my novel machine, illustrating it in use;

Fig. 2 is a top plan view of the machine;

' Fig. 3 is a fratimentary'medial sectional view illustrating e angem'ent of the two helmets and the direc dns of. the currents of heated air; and I Fig. 4 is a plan view of the perforated baflle plate which may be utilized if desired.

Referring now to the drawings ticular description of the invention, my novel hair drier is constructed in the form of 'a Fixed within the helmet 1 is a second hel met 6, adapted to also receive a portion of the head, as illustrated in Fig. 1. This helmet 6 has an outlet 7 at the top of the helmet 1, in which outlet is adapted to fit the sleeve 8 of a flexible pipe 9, said pipe 9 having a sleeve 11 on its opposite end adapted to fit into a casing 12 aflixed to the side of the.

blower chamber 4 and over the opening usual] utilized as an air inlet for said blower.

Vhile I have illustrated a flexible pi e 9, it will be appreciatedthat this is for 1 lustrative purposes only and that I am not limited thereto.

When in use the" helmet 1 is placed over the head, as illustrated in Fig. 1, in which position a portion of the head will preferablv enter t e helmet 6, as clearly illustrated. ereupon the motor is started, and the fan 5 will force a current of air through the sleeve 3, which current of air-will pass the electric heater 13. This heated current of air passes in the direction of the arrows 14 illustrated in Figs. 2 and 3.-- Y

The current of heated air will then strike the inclined walls of, the internal helmet 6, and will be deflected downwardly around the inner walls of the helmet 1, as indicated by the arrows 15.

Meanwhile, however, the fan 5 will be exerting a suction through the casing 12, and

will thus suck the ,air through the pipe 9.

This suction will be sufliciently strong so that the heated air will only pass a short distance below the bottom of the helmet 1 before the suction will draw it upwardly, into the'helmet 6, as illustrated by the arrows 16, whence it will pass through the outlet 7 and pipe 9 to the casing 12 as indicated by the arrows 17, and thence into the blower and back through the sleeve 3 and helmet 1. Thus a continuous circulation of the heated air is created, and as said air is sucked upwardly into the helmet 6, it will penetrate under and I through the haiF'of the person under treat ment, thus causing a thorough permeation of the heated air through the hair of said person, and efl'ecting a quick, efiicient and for a'par- I desired, I may position a baflle plate 18 provided with a plurality of perforations 19 in" the helmet 6, this baflle' plate being spaced from the inner walls of said helmet by webs 20, and secured to the said inner walls of the helmet 6 by lugs 21 in any desirable manner, as by soldering, welding, brazingfifiveting or the like. I 0 effect of this bathe late 18 will be to cause the major portion 0 the air under sucthe edges of the baflle plate 18, while still permitting a suflicient amount of said heated air under suction to pass over the top of the head of the person under treatment to effect a thorough drying of that portion of the head and hair. I

The advantages, efliciency, thoroughness and econom of my novel machine, and of the complete circulation of heated air, and the com ined blowing and suction thereof, will be instantly apparent to those skilled in the art, and the merits of my novel machine have-already been established and proven.

W'hile I have necessaril described m present invention somewhat in detail, it wi 1 be appreciated that I may vary the size, shape wide limits without departing from the spirit of the invention.

M invention is further described and defin' in the form of claims as follows:

1. In a hair drying machine, a helmet adapted to fit over a portion'of a head, a second helmet within said first helmet, means to create a continuous current of air downwardly through said first helmet and upwardly through said second helmet, and a baflle late-positioned in said second helmet to defl ect the major portion of the ascending air to adjacent to the 0nd helmet.

2. In a hair drying machine, a helmet adapted to fit over a portion of a head, a second helmet within said first helmet, means to create a continuous current of air downwardly through said first helmet andv upinner walls of said secwardly through said second helmet, and a perforated baflle plate positioned in said see- 0nd helmet to deflect the major portion of the ascending air to adjacent to the inner walls of said second helmet.

In testimony whereof,I have signed my;
